The password from the end of OoS creates a Linked game in Oracle of Ages. All of the rings and other stuff Link had at the end of that game are carried over.

They say this tower is being made to guide Queen Ambi's lover back to her, but now everyone's starting to hate this tower, and they've started calling it the Black Tower.
